Middle-aged newlyweds Larry (John Saxon) and Barbara (Lynda Day George) spend their honeymoon at a palatial Caribbean mansion, unaware that it is inhabited by the vengeful spirit of a notorious voodoo witch queen who was murdered a century ago. The woman's evil spirit promptly begins precipitating a variety of violent deaths in accordance with a diabolical ritual intended to bring her back to life -- a process which is ultimately consummated by taking possession of George's body. Writer/director Herb Freed's good use of the tropical locations and a moody score by Pino Donaggio provide some interest, though the stilted dialogue and sluggish pacing defeat any real suspense.
